Abstract: Systems and methods for user equipment (UE) for inter-device communication authorization and data sniffing in wireless communication systems are provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. The UE may receive data sniffing related parameters corresponding to the inter-device communication link from a network entity, e.g. a mobile management entity (MME). The UE may store data exchanged over the inter-device communication link in a buffer and upload the stored data to a secure server in a network periodically or upon receiving a request from the network. Long term evolution (LTE) downlink or uplink radio resources may be used for the data exchange over the inter-device communication link.

Abstract: There is provided a method and apparatus for coordinating cells in a heterogeneous network. A serving cell determines scheduling parameters for scheduling a UE intermittently between a serving cell and at least one coordinating cell. The scheduling parameters define a cycle for the UE in which the UE alternates between listening to the serving cell and each of the coordinating cells. Timing offsets between the serving cell and the coordinating cells is determined by a UE and reported back to the eNB of the serving cell.
